I migrated my account back in June, got a mail saying it was successful and didn't think more of it. Today after not playing MC since 2019 I felt like playing again after seeing that Tekkit was back. However when I log into my Microsoft account, my only Microsoft account, all I get is the option to buy the game again, even though I've owned the game since early Alpha.
I've tried contacting support, but the reply I got said they don't help with migration related issues anymore.
Anyone have had the same issue as me? Is there any hope to resolve it or am I SOL?
Are you going through Microsoft support or Mojang support?
I think you should talk to Mojang about this. They're more likely to listen to someone who paid for Minecraft when it was in alpha.
I was playing since alpha, but I didn't buy until beta. When I migrated my account years ago, it was not a smooth process and it took several hours to get my Minecraft purchase to be applied to my new account. I think I just followed troubleshooting written by another player who had the same problem, I don't remember talking to Mojang or Microsoft about it.
